The Nvidia GTX 980 is the new top end Maxwell based Nvidia GPU. The Maxwell architecture offers significantly higher clock for clock performance when compared to Kepler based cards from the previous generation. Comparing the GTX 980 and GTX 970 shows that the 970 only lags by around 17% in terms of performance but it's priced nearly 40% lower making the GTX 970 far better value for money card. Even though the GTX 970 beats the 980 in terms of value, the 980 still destroys previous generation cards. Comparing the GTX 980 and 780 Ti shows that the Newer 980 offers around 14% better performance at a 25% price discount. Nvidia have changed the price/performance landscape with their new Maxwell architecture and now pose a serious threat to AMDs high end GPU market share. The new GTX 980/970 cards replace the now discontinued GTX 780 Ti, 780 and 770. [Sep '14GPUPro]

NVIDIA's GTX 1660 follows hot on the heels of last month's release of the GTX 1660 Ti. As the name would suggest, the 1660 is a slightly scaled back version of the 1660 Ti. Both feature NVIDIAs's new TU116 Turing based die, have 6GB of VRAM, are without RTX cores and have a power draw (TDP) of 120W. The main differences arise from the number of CUDA cores: the 1660 has 1408 whilst the 1660 Ti has 1536, and memory bandwidth: the 1660 can deliver 8 Gpbs using ubiquitous GDDR5 (as featured in the GTX 1060 3GB and 6GB) versus the 1660 Ti which can deliver 12 Gpbs using newer, faster and dearer GDDR6. Early benchmarks show that the GTX 1660 has about a 20% lower effective speed than the 1660 Ti, but with an entry price of $219 USD, the 1660 is also about 20% cheaper. Further, the 1660 has a 12% effective speed advantage over the ~$230 USD 6GB 1060 and a similar real world effective speed to AMD's $265 USD RX 590. NVIDIAs strategy of offering great value Turing products at all price tiers can only be good for competition and consumers. [Mar '19GPUPro]
